Twisting-head.



'finissant fg! Buiten, acitizen otlieUni'ted'States, residing atzthecit'y of Eaiwtu'cketdn the county of Providence and State'of lRhode island, haveinvented ertain nets7 and useful Improvements in l2-WistingfHeads -for .Thread-DressingMachines, 'oi' j which the following is a, specification.

Thisinvention relates to a twistinglh'ead,

.adapted for a 'thread-dressing' machine,` and.

hasfor its object to provide a device of simple onstruction and arrangement of parts,so that .ag large numberA of twisting-headsinay be mounted on the framey o the machine and` :each .operating independent of. the other.

*5A further object of thev invention is to prov yvid'emeans it'orfftheready yinsertion of a thread 1totheftwistingeheadin case' of Abreakage o'fthe thread during the Operation'ot' the device.l
